T 0 all whom 2'25 may concern:

Be it known that I, Varmint E. SMITH, a citizen of the United States,residing at Boston, county of Suffolk, State of Massachusetts, haveinvented an Improvement in Antiseptic Nest-Eggs, of which the followingdescription, in connection with the accompanying drawing, is aspecification, like characters on the drawing representing like parts.

This invention relates to nest eggs of that type which are adapted tocontain an insecticide or antiseptic p "eparation and which is providedwith apertures through which such preparation or the odor thereof mayescape.

The objects of the invention are to provide a novel nestegg which is soconstructed that the insecticide therein will be agitated or stirred upby any rolling motion which the egg may have, and also to provide anovel construction whereby the antiseptic preparation is prevented fromsitting out too freely through apertures in the egg.

I will first describe some embodiments of my invention and then pointout the novel features thereof in the appended claims.

In the drawings, Figure 1 is a central sectional view of an eggembodying my invention; Fig. 2 is a similar view showing a difl erentembodiment of the invention; Fig. 8 is a perspective View of one of thedisks or partitions shown in Fig. 2.

Referring first to Fi 1 the body or shell of the egg is shown at 3 andit may be of any suitable material. This shell or body is made with theinterior chamber 4 which is adapted to receive an insecticide orantiseptic preparation 5 that is preferably in the form of a powder. Theshell or body 3 may conveniently be made in two sections which areunited together at the joint 6 by cement or in any other suitable way,although said body might be formed in any appropriate way withoutdeparting from the invention. The body 3 is provided with a plurality ofapertures or perforations 7 through which the insecticide 5 and the odorthereof may escape. In order to prevent the insecticide from sitting toofreely out through the apertures 7, I have'provided the body 3 on itsinterior with the projections 8 through which the apertures 7 extend sothat the inner end of each aperture is at the inner end of theprojection. As one convenient way of making the egg I insert through thebody 3 thereof a plurality of tubular mem bers 9, the inner ends ofwhich constitute the projections S and the bores through whichconstitute the apertures 7. These projections 8 also serve as a meansfor stirring up and agitating the insecticide 5 as the egg is rolledabout the nest, and they are thus effective in preventing theinsecticide from caking or hardening. This is a decided advantage, forin order to be efiective, the insecticide should retain its dry powderycondition in order that whenever the egg is rolled or moved about thenest, the dust from the insecticide and the odor thereof may escapethrough the apertures 7. In Fig. 2 I have shown another embodi ment ofmy invention wherein means are also provided for stirring up theinsecticide as the egg is rolled about the nest. In this embodiment theegg body, which is shown at 3, and which may conveniently be made in twosections, joined together at 6, as above described, is provided with twopartitions 10, one in each section of the egg, which partitions dividethe interior of the egg into two insecticide-receiving chambers 11 and acentral distributing chamber 12. The body of the egg is provided withthe tubular members 9, the ends 8 of which project into theinsecticide-receiving chambers 11, each tubular member having the boreor passageway 7 through which the insecticide may escape. The disks orpartitions 10 are provided with openings 13 through which theinsecticide may gradually escape from the chambers 11 to thedistributing chamber 12, and these openings can conveniently be made byslitting the partition 10 along the line 14, and then striking up theportion 15 adjacent the slit to form a cup or pocket. The body of theegg is provided with other apertures 16 leading to the exterior or. theegg from the distributing chamber 12 and through which any insecticidewhich passes to the distributing chamber may escape.

lVhenever an egg constructed as shown in Fig. 2 is rolled about the nestthe insecticide powder 5 which is confined in the chambers 11 will beagitated and stirred up, partly by the projections 8 and partly by thecup-shaped portions of the parti tions 10, and part of the powder willescape through the apertures 7 and some will be delivered into thedistributing chamber 12, from which it will escape through the apertures16. I11 this embodiment of my invention also the insect-icidepreparation is kept agitated by the turning movement of the egg so thatthe chambers within the egg will be more or less filled with clouds ofdust or powder which are caused by the agitation of the insecticidepreparation, and this dust will escape from the apertures in sufficientquantity to kill any lice or other vermin which may infest the nest orthe hen.

I am aware that it has heretofore been proposed to make nest eggs withan interior chamber to hold insecticide and apertures through which theinsecticide may escape, but my invention aims to provide means situatedwithin the egg for preventing the insecticide from caking and forcausing it to be stirred up more or less violently when the egg isrolled so as to develop a considerable quantity of dust.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is 1. In a nest egg, the combination with abody having an insecticide-receiving chamber, of insecticide in the formof a powder partially filling said chamber, and a plurality ofopen-ended tubular members extending radially through the walls of thebody and into the chamber a suflicient distance so that those on theunder side of the egg will pass through and terminate at their innerends above the mass of insecticide whereby as the egg is rolled or movedthe insecticide powder is stirred up and agitated by the tubular membersthereby form-- ing a dust which escapes through said members.

2. In a nest egg, the combination with a body having an interiorchamber, of apertured partitions extending across the body and dividingits interior into insecticidereceiving and distributing chambers, andmeans within the insecticide-receiving chamber to cause the insecticidetherein to be stirred up and agitated when the egg is rolled, said bodyhaving apertures leading to the distributing chamber.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
